L-GaN
Revision 0
Introduction 1–6
1.3.14 Block Up Converter (BUC) Input
The LGaN upconverts an L-Band input carrier to the desired output frequency (C, X, or Ku-Band). LO
frequencies are provided in the table below:
BUC C, Ku, X LO Frequencies
Band Frequency LO Frequency Inverting
C-Band
5850 to 6650 MHz 4900 MHz No
5950 to 6700 MHz 5000 MHz No
Insat C-Band 6725 to 7025 MHz 5760 MHz No
X-Band 7900 to 8400 MHz 6950 MHz No
Ku Band (Low) 12.75 to 13.25 GHz 11.800 GHz No
Ku-Band 14.00 to 14.50 GHz 13.050 GHz No
Ku-Band-W 13.75 to 14.50 GHz 12.800 GHz No
Unlike most BUCs, no DC bias voltage should be provided on the center conductor of the L-Band coax. In
addition, the LGaN is available with an internal 10 MHz reference. As, such, no 10 MHz reference is
required on the center conductor of the L-Band coax. If a reference is provided on the coax, the internal
reference will detect and lock to it.
